Fluorinated Surfactants

Fluorinated Surfactants in EOR application is also an important research direction.Oil processing structurally different from conventional surface active agent of the main features of the hydrogen atoms on the hydrocarbon chain, all or partially substituted by fluorine atoms to form a perfluorocarbon-containing fluorocarbon chain or a chain containing fluorocarbon chains can contain both If O? S? N? Si and other atomic and molecular structure of the other parts of the classification and the surface active agent are identical with conventional surfactants. Since the chemical properties of fluorine atoms in the molecular structure of the partially fluorinated or perfluorinated group substituted with the general nature of the various substituents, the molecule caused by the physical and chemical properties change dramatically. machine for pellets surface active agent, and its excellent performance and unique "three high" high surface activity that? Thermal stability? High chemical inertness and "two hate" that is hydrophobic oleophobic, another complex and with less good performance ? toxicity is low or very low and so is its prominent feature is the high cost of insufficient, you can use less to make up, so in addition to the chemical? machine? textile? paint? firefighting and other fields have a wide range of applications, particularly in the oil industry is EOR flooding in its capacity as a surfactant application effect also attracted attention.
